[PATCH] nls: fix byte order conversion warnings in get_utf16()

[HsuehBo]

From: Hsueh Bo <HsuehBo@126.com>

Add proper __force type casting to resolve sparse warnings
about restricted __le16/__be16 conversions in get_utf16() function.

This fixes the following sparse warnings:
fs/nls/nls_base.c:180:24: warning: cast to restricted __le16
fs/nls/nls_base.c:182:24: warning: cast to restricted __be16
